Positioning device for positioning a patient

Abstract

A positioning device is applied in a reproducible manner to a patient, allows indication of the position of an anatomical area of the patient, allows the patient to be positioned in a reproducible manner in relation to an examination area of a medical examination device and a therapy area of a therapy device, and includes an antenna arrangement for the examination with a magnetic resonance device. In one embodiment, the positioning device also includes an arrangement for immobilizing the patient.

Description

BACKGROUND OF THE INVENTION [0001] The present invention relates to a positioning device for positioning a patient in relation to a medical examination or therapy device. The device is configured for multiple use by a plurality of patients and comprises means for indicating the position of an anatomical area of one of the patients in relation to the positioning device and means for the reproducible positioning of the patient in relation to an examination or therapy area of the medical examination or therapy device. [0002] The positioning of a patient to be examined or treated correctively in relation to an examination or therapy device is essential for the effectiveness of a treatment. The positioning requires a correspondingly high level of accuracy. When carrying out complex treatments, for which examination and therapy devices are deployed in an alternating manner, reproducible positioning of the patient is of crucial importance. One example of such a complex treatment is radioth...

Benefits of technology

[0012] The positioning device according to the invention is simple to operate and can be deployed in a time-saving and economical manner. Areas of application for the positioning device include, for example, MR, CT and ultrasound examinations as well as radiotherapy. The positioning device is preferably configured for economical multiple use by one or a plurality of patients.

[0029] An antenna arrangement present according to the invention acts as a high-frequency MR antenna arrangement in proximity to the organ to provide optimum resolution and good image quality. An additional advantage is the reliable and precisely reproducible position of the antenna arrangement in relation to the anatomy. In one advantageous embodiment, the positioning device comprises an antenna arrangement that can be positioned in a reproducible manner for examinations with a magnetic resonance device. The antenna arrangement can preferably be located in a reproducible manner on the positioning device. This can be achieved, for example, using a pocket in the positioning device, and the antenna arrangement is inserted into the pocket. In the event that it is not required, for example during a CT examination, the antenna is removed from the pocket.

Problems solved by technology

Such markings can be lost over time, for example if the patient is cleaned with alcohol.

This is very time-intensive and there is a risk of incorrect positioning.

Poor positioning results in an avoidable, additional radiation load due to inaccurate radiation and additional CT control examinations.
